在本文中，我们考虑了受相位噪声影响的通道的螺旋星座设计。所提出的星座的优势在于性能和设计的极端简单性。这些符号实际上可以用解析形式表示，并且通过考虑相位和热噪声方差的单个参数来唯一定义。所提出的星座的结构允许轻松确定最接近复平面中任何点的点，因此我们还提出了一种低复杂度检测器，适用于中高信噪比条件下的相位噪声通道。所提出的星座的性能是根据信息率和错误率来评估的。尽管很简单，但新的螺旋星座具有出色的性能，特别是当星座尺寸变大时。
In this paper, we consider the design of spiral constellations for channels affected by phase noise. The strength of the proposed constellations resides both on the performance and on the extreme simplicity of the design. The symbols can in fact be expressed in analytical form, and are uniquely defined through a single parameter that accounts for the phase and thermal noise variances. The structure of the proposed constellations allows to easily determine the points that are closest to any point in the complex plane, therefore we also propose a low complexity detector that is suitable for phase noise channels in medium-high signal-to-noise ratio conditions. The performance of the proposed constellations are assessed in terms of information rate and error rate. Despite their simplicity, the new spiral constellations have excellent performance, especially when the constellation size grows large.
